USBTrace : USB Protocol Analyzer Software for Windows

Easy to use
USBTrace is an easy-to-use USB protocol analyzer. To analyze a USB device, just select the device and click the 'capture' button. See USBTrace Quick Start Guide.

Sniffs USB requests at all levels
With USBTrace you can analyze USB protocol traffic at USB Host Controllers, USB Hubs and USB devices. The tool captures and displays USB Control, Bulk, Interrupt & Isochronous transfers.

Displays detailed device information
USBTrace decodes and displays both standard and class specific USB descriptors (Device, Hub, Configuration, Interface, Endpoint, Class Specific, IAD, String) and Windows enumeration information.

USBTrace does not use any filter drivers
Unlike other software based USB analyzers, USBTrace does not use any filter driver to capture the USB requests. So USBTrace will not disturb/slow down the PnP system due to its presence.

Captures all USB protocol data during device enumeration
USBTrace is capable of capturing all USB requests exchanged between the host controller/hub and the device during device enumeration. See USB Enumeration Explained to know how USBTrace is different from other USB monitor software.

Define your own data decoding templates in XML
In addition to automatically decoding standard/class specific USB requests/descriptors USBTrace also lets you define custom templates for decoding data buffer of requests in XML. Know more

Displays valuable information for device driver developers
The IRP, URB and IO_STACK_LOCATION structures associated with each captured request is decoded and displayed by USBTrace. Also, in addition to capturing URBs, USBTrace captures Internal USB IOCTLs, User mode USB IOCTLs, PnP and Power IRPs. See Complete List of USB requests captured by USBTrace.

USBTrace also allows device driver developers to capture USB requests made/received by any device object in the USB device stack.

Supports device class decoding / Write your own vendor specific class decoder
USBTrace can decode class specific usb descriptors/requests and display detailed information regarding them. The classes currently supported are Hub, HID, Mass Storage, Bluetooth, Wireless USB HWA, Still Image Capture, Printer, Audio, Video, Smart Card, Vendor specific device class etc. Read more about USB device class decoding

Export Captured Data & Detailed Device Information
Captured data can be exported as HTML, XML, Text or CSV reports. Detailed device information can also be exported. This feature will help you to document the device behavior as well as to share the captured data/device details in an easily readable form with others.
